Abstract
The utility model discloses a novel oil distributing valve for an ultra-high pressure radial piston pump. The novel oil distributing valve for the ultra-high pressure radial piston pump comprises an oil distributing valve body, an oil outlet is formed in one side of the oil distributing valve body, a lower pressing cover is embedded at the lower end of the oil distributing valve body, an upper pressing cover is embedded at the upper end of the oil distributing valve body, and oil inlets are respectively formed in the lower pressing cover and the upper pressing cover. A lower conical surface pad, a lower steel ball, and a lower guiding rod are arranged from top to bottom between the lower pressing cover and the oil distributing valve body. An upper conical surface pad, an upper steel ball, and an upper guiding rod are arranged from bottom to top between the upper pressing cover and the oil distributing valve body. The number of parts which are used is greatly reduced, the structure is simplified, the number of times of parts connecting and matching can be reduced, oil leaking spots is reduced, the structure is more reasonable, a seal mode of linear rigidity seal is adopted among all the parts, so that operation is more reliable, more pressure can be born, leakage is not prone to happening, operation requirements of high pressure can be met, damage rate is reduced, and the overall working efficiency of a radial piston pump is improved. The novel oil distributing valve for the ultra-high pressure radial piston pump can meet the development requirement that operating pressure and flow of the ultra-high pressure radial piston pump increase constantly.
Description
Technical field
The utility model belongs to superhard material synthetic hydraulic system technical field, particularly a kind of novel ultrahigh pressure radial plunger pump oil distributing valve.
Background technique
The structure of existing Ultra-high Pressure Radial Piston Pump oil distributing valve is combined type, its structure and assembling mode as shown in Figure 2: mainly by oil distributing valve body 13, lower seal gland 14, delivery valve seat 15, fuel-displaced spool 16, spring 17, cross oil pipe 18, delivery valve seat 19, fuel-displaced spool 20, spring 21, gland 22, upper sealing gland 23 and copper washer and O RunddichtringO and back-up ring and consist of.In this structure, the sealing of lower seal gland 14, delivery valve seat 15, delivery valve seat 19 and upper sealing gland 23 and oil distributing valve body 13 inwalls is realized by O RunddichtringO and back-up ring.
There is lower column defects in the oil distributing valve of said structure: 1, oil distributing valve body 13 mounted inside have a plurality of component, and component are more, cause Ultra-high Pressure Radial Piston Pump easily to produce vibrations, easily cause damage of equipment when work; 2, lower seal gland 14, delivery valve seat 15, delivery valve seat 19 and upper sealing gland 23 are sealed by the O RunddichtringO with oil distributing valve body 13 inwalls, along with the raising to the whole working pressure of plunger pump radially, above-mentioned sealing means can not satisfy usage requirement, needs often to change O RunddichtringO and back-up ring; 3, damage if there is oil distributing valve body 13 inner components, need to dismantle all component during maintenance, keep in repair cumbersome; 4, the oil distributing valve of this structure is seriously restricting the raising of the whole working pressure of radial plunger pump, continuous expansion along with cubic apparatus press synthesizing cavity, working pressure and flow to Ultra-high Pressure Radial Piston Pump also constantly increase, make the oil distributing valve of this structure not satisfy the demands, be faced with the condition that is eliminated.
The model utility content
The utility model provide a kind of rational in infrastructure, bearing capacity is strong and non-damageable novel ultrahigh pressure radial plunger pump oil distributing valve.
For achieving the above object, the technical solution of the utility model is: a kind of novel ultrahigh pressure radial plunger pump oil distributing valve, comprise the oil distributing valve body, oil distributing valve body one side is provided with oil outlet, described oil distributing valve body lower end is inlaid with lower cover, the upper end is inlaid with upper press cover, is respectively equipped with oil outlet on lower cover and upper press cover; Be provided with successively from bottom to top lower conical surface pad, lower steel ball and lower guide rod between lower cover and oil distributing valve body; Be provided with successively from bottom to top conical surface pad, upper steel ball and upper guide rod between upper press cover and oil distributing valve body.
compared with prior art, the utility model has the advantages that: the utility model comprises the oil distributing valve body, oil distributing valve body one side is provided with oil outlet, and described oil distributing valve body lower end is inlaid with lower cover, the upper end is inlaid with upper press cover, is respectively equipped with oil outlet on lower cover and upper press cover, be provided with successively from bottom to top lower conical surface pad, lower steel ball and lower guide rod between lower cover and oil distributing valve body, be provided with successively from bottom to top conical surface pad between upper press cover and oil distributing valve body, upper steel ball and upper guide rod, the component number of its use greatly reduces, structure is simplified, can reduce component and connect the cooperation number of times, reduce the leakage of oil point, structure is more reasonable, all adopt the sealing means of linear hard sealing between all component, work more reliable, can bear higher pressure, and be difficult for leaking, can satisfy the usage requirement of high pressure, and can reduce spoilage, improve the whole work efficiency of radial plunger pump, can adapt to the growth requirement that Ultra-high Pressure Radial Piston Pump working pressure and flow constantly increase.

Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model prior art.
Embodiment
Novel ultrahigh pressure radial plunger pump oil distributing valve as shown in Figure 1, it comprises oil distributing valve body 1, is provided with oil outlet 6 in oil distributing valve body 1 left side.Be inlaid with lower cover 2 in the lower end of oil distributing valve body 1, lower cover 2 is provided with oil outlet 4, is provided with successively from bottom to top lower conical surface pad 7, lower steel ball 8 and lower guide rod 9 between lower cover 2 and oil distributing valve body 1.Be inlaid with upper press cover 3 in the upper end of oil distributing valve body 1, upper press cover 3 is provided with oil outlet 5, is provided with successively from bottom to top conical surface pad 10, upper steel ball 11 and upper guide rod 12 between upper press cover 3 and oil distributing valve body 1.
The utility model component number greatly reduces, be simplified, can reduce component and connect the cooperation number of times, reduce the leakage of oil point, structure is more reasonable, all adopt the sealing means of linear hard sealing between all component, make this structure can bear higher pressure and not leak, satisfy the usage requirement of high pressure.
